Automakers Seek to Resurrect Bush Fuel Economy Regs

Meeting that a 35 mpg fleet economy goal by 2020 is expected to cost the industry tens of billions of dollars as it develops new cars and revamps plants.

WASHINGTON -- Auto makers are pressing U.S. regulators to adopt fuel-economy rules drafted by the George W. Bush administration after U.S. President Barack Obama signaled this week he may impose stricter standards.

A set of rules drafted by Bush officials last year would require all cars and light trucks on U.S. roads to meet an average fuel economy of 31.8 miles per gallon by 2015, up from about 25 mpg today. Bush officials had planned to finalize the rules but ultimately left the task to Obama.

The auto industry initially opposed the drafted standards, saying regulators were being too aggressive in their effort to improve fuel economy. Now, the industry is strongly backing them.


Powered by a 100 kW electric engine and fuel cell stack, the i-Blue is capable of running more than 370 miles per refueling and achieves a maximum speed of more than 100 miles per hour.

Based on the full-size 2007 Chevrolet Silverado 1500 HD pickup truck, the vehicle underwent extensive internal modifications to meet the technical demands and requirements needed to run on a compressed hydrogen fuel system.

In the Quadrivium Fuel Cells system, the various components are distributed around the car, with four fuel cells positioned near to the wheels.
